Patent CA-2123752-A1 (CA)
Inventor: BERGEVIN BENOIT
IPC: H02S40/12
Filed: 1994-05-17
Abstract: This invention relates to a photovoltaic system comprising a casing having mounted therein a plurality of solar cells. The casing has a front and opposite thereto, a rear. The front of the casing is provided with a light-transmitting panel for transmitting solar light to the solar cells. The rear is a double wall. A first wall is in contact with the back of the solar cells, and on its side away from the solar cells is of a dark-opaque colour, heat-absorbing surface.          The second wall is a light-transmitting enclosure of the dark-opaque colour side of the first wall, but spaced therefrom so as to produce a greenhouse effect. A method to remove snow, frost and ice over a photovoltaic system involves maintaining the light-transmitting panel at an angle with the horizontal, receiving reflected solar rays from the surroundings of the photovoltaic systems through the light-transmitting enclosure to the outer side being dark-opaque colour to be absorbed by the outer side and converted into heat to be transmitted to, and thereby to raise the temperature of the light-transmitting panel. Simultaneously the light-transmitting enclosure creates a greenhouse effect and thereby  an additional temperature increment to further raises the temperature of the light-transmitting panel to melt or sublimate snow, frost and ice present thereon.

Title: Ground fault circuit interrupter incorporating miswiring prevention circuitry
Inventor: NEIGER BENJAMIN
IPC: H02H3/04
Filed: 1994-07-04
Abstract: A ground fault circuit interrupter (GFCI) with built in intelligence is described that includes circuitry to automatically indicate a device miswiring condition. When a GFCI is wired with its AC and LOAD terminals reversed, downstream devices are still protected in the event of a ground fault but the duplex receptacle on the GFCI  itself is not. The invention incorporates miswiring sense circuitry that automatically triggers the generation of visual and audible alarms in the event a miswiring condition is sensed. The invention employs an alarm inhibiting technique that incorporates sense circuitry connected to the AC terminals on one side of the internal GFCI  switches or relays and alarm generation circuitry connected to the LOAD terminals on the opposite side.

Title: Anti-inflammatory peptide analogs and treatment to inhibit vascular leakage in injured tissues
Inventor: WEI EDWARD T
IPC: C07K14/575
Filed: 1993-08-04
Abstract: Small, anti-inflammatory compounds that are peptide analogs are described useful to inhibit inflammation of a mammal's skin, mucous membranes, or lacerations of the musculature or injury to the brain or leakage of fluids into the air spaces of the lungs. Peptide analogs of the invention have the primary sequence TN-A1-A2-A3-A4-A5-A6-Tc where one of the moieties is in the D-configuration. A1 and A2 are each a basic polar amino acid while each of A3, A4, and A6 is a hydrophobic amino acid. A5 can be a variety of structures and appears to function to optimize the spatial relationship between the hydrophobic and the basic residues. TN is selected or modified to convey resistance against enzymatic degradation. Tc is an amino group or an amidated amino acid, preferably hydrophobic.
